Movespeed quints are a big nono on any support. Also, start Doran's Shield - it is op.

Sorry for the late response, but is there any way to avoid that "wall of text" problem? The best I can think of is using pictures as they do show a thousand words. Again, new to this so a strong push into the right direction is going to help a lot.

^ my god.

Hey dude ^_^ Okay, where to begin... Remember, since I'm your friend, I get to be as mean as possible and you can't get mad at me, okay? :D

• Small thing, but in your top cheat sheet, you might want to make your marks first, not your seals.
• Another small thing in your cheat sheet: Try making your items in buying order. For example, for your end build, begin with boots, then sightstone, then talisman/locket, then etc. This'll make it more clear to potential readers when they skim through your guide as they recall. They won't have time to read through your ENTIRE guide in the 5 seconds they have before heading back to lane.
• Have you considered running 0/21/9 masteries instead? I mean, Leona is a tank after all, and the early survivability is good if she comes out of a bad trade.
• The little pictures with jokes are funny and cute, buuuut not necessary. Put them in spoilers to shorten the guide. It'll also take away from the actual information in the guide itself.
• Lore-->Spoiler. And the "Rewording the lore" part xD Though your version is funny, it's (once again) not necessary.
• Ooh. That Pros/Cons list doe. So much blank spaces... Try putting it in horizontal columns instead like:

• And while we're on that subject, you should really consider taking out some of those o.O You have a lot and some of them are pretty self explanatory. For example: "the can go okay/really good" should be discussed in your match up section. Not your Pros/Cons.
• Same thing with with the Pros/Cons section for your Runes. Try using columns. It'll take out a lot of the blank spaces in your guide, making it shorter without losing the details.
• Ooh your masteries. I'm not gonna go into detail about them in specifics, but please fix the walls of text :/ It's hard to read, especially with all of the links to the database. Try using the [list] function to organize it better.
• Summoner spells, use the [icon] code. It'll draw attention to the spells you're discussing. Also, don't discuss your abilities in the "Summoner Spell" section... That's supposed to be in a different chapter!
• Your items. Need. To. Be. Fixed. Go back to your coding and add blank "Enter"s so that they'll even themselves out. Don't see what I mean? Click here to see an awesome example of what it could look like.
• You should probably leave the consumables last in the items list. They're most likely the least important, so instead of going Health Potion--> Stealth Ward--> Stealth Ward--> Ancient Coin, make Ancient Coin first in the list to emphasize it's importance.
• Try using dividers! [-----]
• For your abilities, you might want to try putting the information about like, cooldown/mana cost/description separate with an extra line in between or different color. The italics make it hard to read. Here is yet another example from the same guide I referenced earlier. Scroll up a bit.
• Early Game section: Watch the walls of text! Use columns to add pictures of the examples to liven things up! If you need me to, I can play as Lulu and let you kill me as you demonstrate the combos ^_^
• The "Few important things to think of before you engage" should be in a different section entirely, IMO. Make like, a "Decision making" or "General supporting" section to discuss that kind of stuff.
• Your mid game section is fine, although I'd recommend choosing just one color, like Bright Green, to show that these are the important things you should be paying attention to. This'll give it a sense of uniformity.
• When you're writing about objectives, use Capitalization. The codes don't do it automatically for things like Baron or Dragon xD
• Support Matchups? I like the titles xD They made me laugh quite a bit. Although, I don't think you should make entirely different lines for each one. Same guide. Look at it! :D Pretty, no?
• Same thing with your ADC lane matchups.

You know what? I'm just gonna leave it there xD I wrote a lot. Even more than I typically do for my comments, and that's really saying something. These are just suggestions, but I do highly recommend you consider them. They'll make your guide even more amazing. And don't get me wrong! You're guide is awesome :D It's in depth with a touch of humor to keep it interesting. I'm just throwing some ideas that might make it more easy to read.

Annnnd yeah. Soo, good job! Upvoted for the amazing amount of effort put it! :D

Matchups made me laugh.

• Masteries section are kinda walls of text :/
• Early game section is are some walls of text
• "What you should do" wall of text :(
• Very detail, props for that
• Could use some images to keep it interesting (your guide is very long as you said and 90% of the readers won't actually read it all)

Best of luck to you!

Just a couple of things:

• I recommend putting the lore in spoilers.
• The texts for Pros and Cons feel like they are one paragraph. Separate them, not necessary, but it would be more visually appealing.

Also for the next guide you make, try to cover the most important topics, and leaving out the unneeded ones. Think about it, your guide is very long.
